In the accompanying (lrawinge, Figure l is a side elevation of devices szlloiviiig;F one lorln oi -lny invs'lyition; and Fig. 2 is an end View of Said devices.

Like numerals designate similar parte throughout the Severai views.

Referring to the drawings, the nunierai 1 designates a slide on the carriage of the nio.- ehine (not Shown), and clamped in place adjnatably on seid carriage by means ciesig hated' in e general way oy 2, and to which .no claim of invention is niafle in the presen;

ease. Adjust-ably fitted in the iop of the slide 1 .is another slicle, which acts as a support -for the devices te he hereinafter' (leseribed, and depending; :trein this slide 3 isan extension hearing absiinet a springaetuated plunger 5 fitted in o, bore of said slide l. A screw (3 is in a bore of the slide 1, sind .e thumb-nut 7 engages said screw and permitsl a free adjustment of Said slide 3 to 'ne made, the hub of said thumb-nuthearing against a rejection 4 on said slide 3.

I.itising from the slide 3 is a standard 8, and secured to said standard by screws Sis o vertical support 10 having an inclined arm- 11. Pivotecl at 12 to the vertical support is an arm or lever '13 grooved as shown in' dotted lines at 14 to receive u relier 15. Fitted in grooves of said inclined arm 13 is a Weight 16 adjustably Secured at any point along the bottoni of the arm by a screw '1T or in any other desired manner. A1". the inner end arln 11 is provided with a noe er shoulder 1S and projecting troni the slide or support 3 an elongate holt or stud 19. hws 2() formed integral with the .eimport 107 and secured 'ov e pin livin a seat vet 'said nosa a hoh 2Q having a. threacie section :2i-37 and e nut upon said thrcafied section. Sieeved on the bolt 19 e supporter rocket '243 and righi with Seid bracket in an erm QG through which the holt A screw ZT having e thunih-nut QB is threaded into the supporter bracket, 2li, enti Said screw has a 'lip 29 hearing a gainet the enti oit the nose or projection it of tl e are: 13. (ln the inner aide of the suj 'eert or brochet ii is located a shoulder 30, and said Support or bracket aise carries: a nose or projection 31 for engaging an '.rnf. 25:2 projo-enne; freni :i steady rist 3,23 provided with z? l efirably integral iHhoe 34, and 'with singular Stands 35. i This .eteaiivreet 353 loca-toet at an angle preferably ahUUt'iortyive degrees to the exis of the work Se onder process ot' reduction, said work beingl upported hy the usual centers. (Not Shown) inthe operation of the machine the-eerriage thereoIn isinovecl back and forth to cause the grinding-wheel or other reducing agent to operate upon the work, and as Said work is reduced 'it is important to hold the Shoe ot the steady-rest against the same under positive` and nnyieltling pressure and to prevent any back action ot seid steadyrest. which would permit it to leave the son face oi the Work. in the present instance this is mzeoniplished in the following ina-nner :weekwili he eliserveti the supinirt or bracket 2a ie elidnloieupon and guided by `the rofl or holt 1U@ and is limited in its Sliding' movement hy the nut 2i; said rod or boit oonstitutin' i convenient and simple .relatively ixea guide means for the steady-rest support or carrier. To canse this sliding movement of the support the nose of the har 13 Willyiinder the inilnence ott-he roller' 15 sliding in e groove 14 of seid tier 13, `eoncting with title incline 11 onarni 11,A and under the iniuenoe of adjustable Wei 4ht 16 cause seid nose 18 to bear against tie tip -oi' the screw 27 Vand. thereby automatically force the shoe 34C of steady-reet i3 to keep in contact "with ,the Work being reduced yand to qllow up the reiiuction of Seial work.

Stress of the Work in revolving against A as.

the shoe is counteracted by the nose 31 in engagement With the arm of. said steadyrest, thereby preventing the lifting of the anb'ular studs 35 from. their seats in the bifurcated support 25 as Tvill be rgeadily un derstood. A limit to the reduction of the Work .is provided for by the adjustable nut 2e. lt Wiil, therefore, be seen thatthe shoe 34 will follow up the reduction of the Worlr by positive and unyielding mechanical means, and that any vertical adjustment required of said shoe may be obtained by the screw 27,' the top of which is in contact `with the nose 18, and preferably' the slot 3l' in the slide 3 is in the shape of a -slot 'to re eeive a nihead projectin from the support i, as shown by dotter lines in l and 2.

' By the means described. the shoe 34- en;

gages the Work under positive and unyieldlng action and is kept in contact therewith automatically by the arm 13, the rolling Weight l5 and the. inclined arm v1l secured to the standard 8 of the slide.

Changes may be made in the various de tails of the invention Without departure therefrom, said invention not being imited to the precise devices illustrated and dcscribed, but includes Within its purviewT means broadly for holding the steady-rest against the Work under positive and unyielding pressure.
